FAQs on Do All Organisms Respond to Stimuli Video Lecture - Science for Class 6

1. What are stimuli, and how do organisms respond to them?
Ans. Stimuli are changes in the environment that can affect an organism. Organisms respond to stimuli in various ways, such as moving towards food (positive response) or moving away from danger (negative response). These responses help them survive and adapt to their environment.
2. Do all organisms respond to stimuli in the same way?
Ans. No, different organisms respond to stimuli in various ways based on their species and environment. For example, a plant might bend towards light (phototropism), while animals may flee from predators or seek shelter. The type of response varies significantly across the animal and plant kingdoms.
3. Why is it important for organisms to respond to stimuli?
Ans. Responding to stimuli is crucial for survival. It helps organisms find food, escape danger, and adapt to changes in their environment. These responses ensure that they can thrive and reproduce, which is essential for the continuation of their species.
4. Can you give examples of how different organisms respond to stimuli?
Ans. Yes! For example, a sunflower turns to face the sun as it moves across the sky (sun tracking), while a rabbit might freeze or run away when it senses a predator nearby. Fish may change their swimming patterns based on water currents or the presence of other fish.
5. How do humans respond to stimuli compared to other organisms?
Ans. Humans respond to stimuli using a combination of instinctual reactions and learned behaviors. For instance, we might pull our hand away from something hot (instinct) or navigate social situations based on experience (learned). While other organisms also have instinctual responses, humans often have more complex decision-making processes.
